Doug and vicki are working together to convert an equation from vertex form to standard form. they decided to each solve the problem on their own and then compare answers. doug's work is shown below. vicki claims that doug made a mistake. review his work below and choose the correct answer from among the answer choices.
y = -(x - 3)² + 2
step 1: y = (-x + 3)² + 2
step 2: y = x² - 6x + 9 + 2
step 3: y = x² - 6x + 11
doug made a mistake in step 1
doug did not make a mistake
doug made a mistake in step 3
doug made a mistake in step 2
